Peanut proteins: Extraction, modifications, and applications
Peanut oil is typically isolated from peanuts using conventional extraction methods, such as mechanical pressing and solvent (n-hexane) extraction [29]. However, many of the peanut proteins are denatured as a result of high temperatures during pressing or due to exposure to the organic solvent.
The approaches used to the extraction processes of peanut oil is directly affected its quality. Generally, peanut oil can be extracted from shelled and crushed peanuts using various methods such as conventional process includes mechanical pressing, solvent extraction and modern pretreatment methods like dry air heating, ultrasonicating
Comparison evaluation pretreatments on the quality
Cold-pressed walnut oil has a delicate fragrance and retains high levels of nutritional components. However, as the internal structure of the walnut kernel is relatively intact during oil extraction, the release of oils and fats is reduced significantly, which can result in a lower yield of oil (Cai et al., 2021). In contrast, hot-pressed WO
Aqueous enzymatic extraction (AEE) is a new technology for extracting vegetable oil body which has the advantages of low energy consumption, product safety, mild reaction conditions, and simultaneous separation of oil and protein. Among the enzymes tested in the present work, Viscozyme L (compound plant hydrolase) exhibited the highest extraction activity during peanut oil extraction
Genotype × Environment Interactions for Oil Content in Peanut
The cake obtained after extraction of oil is used in animal feed industry, in making enriched easily digestible food for children and aged persons, and as soil amendment. Peanut kernels are nutritious and are a high-energy food, as they contain 48 to 50% of high-quality edible oil and ∼25% protein.
Oil body emulsions (OBEs) affect the final oil yield as an intermediate in the concurrent peanut oil and protein extraction process using an aqueous enzyme extraction (AEE) method. Roasting temperature promotes peanut cell structure breakdown, affecting OBE composition and stability and improving peanut oil and protein extraction rates. Therefore, this study aimed to investigate the effects of
Defatting and Defatted Peanuts: A Critical Review on
A study carried out in 2019 by Suri et al. examined how peanut oil quality char- acteristics were affected by a combination of dry air roasting and mechanical extraction using screw pressing [
Peanut meal, known as defatted meal, is by-products derived from the extraction of peanut oil. The high-protein-defatted meal (>25% protein) can be processed into various food products. In addition, peanut skin, peanut hull, and peanut vine are by-products of peanut oil extraction.
Impact of roasting and extraction methods on chemical
The increase in oil yield of roasted peanut oils may be due to the generation of permanent pores in the cell walls and rupturing of cell walls. The changes in porosity allowed the movement of oil from cell walls and thus increases oil extraction efficiency (Azadmard-Damirchi et al. 2010).
2.2. Aqueous Enzymatic Extraction of Peanut Oil and Protein Peanut oil and protein were prepared using the methods described by Liu [18] and Zhao et al. [19] with minor modiÞ cations. Figure 1 presents a ß owchart of the AEE for peanut oil and protein. For the de-red-coating treatment, the peanuts were roasted in an
